The Q-switched Nd:YAG laser freckle removal machine is radiates the
light of specific wavelengths in high peak energy pulse, and in
ultra-short nanosecond the light penetrates the tissue and is
absorbed by the pigmentand result in an instantaneous blast.The
pigment particles are shattered in to fragments, partsof them will
be bounced out of theskin and the other parts will be spilt into
tiny particles that can be engulfed by phagocytes and then
eliminated by lymphatic system.
